Kutheni ufuna i-grounding, kunye nendlela yokuyixhuma kwindlu yangasese

Cishe zonke izibonelelo ezinxulumene nombane, kubalulekile ukukhusela abantu ekutshitshweni kombane. Wonke umntu uyazi isizathu sokuba kufuneka, kodwa bambalwa abantu bacinga indlela yokuyifaka ngokufanelekileyo, ukuze ifeze ngokupheleleyo imisebenzi yayo.

Ukuba udibanisa zonke iinsimbi zeso sixhobo kwisixhobo esisisiseko, ngoko ke xa i-potential power incitation kuyo, umbane wamandla uya kuhla. Emva koko xa uthinta isinyithi ngomntu uya kudlula okona mncinci kakhulu, kungekhona ukubeka ingozi kuye.

Umbane unikwa njani kubasebenzisi?

Amandla kagesi avela kumthombo ngokusebenzisa imigca yamandla kuqala ukuya kwisithuba, kwaye ke kubathengi. Iifowuni zesigaba ezintathu zisetyenziselwa ukuhanjiswa kwayo. Umqhubi wesine ngumhlaba. Kwinkonzo yesigaba esithathu, i-transformer windings ye-substation ifakwe kwi-"star". Inqaku eliqhelekileyo (ukungathathi hlangothi) elinokuthi linokuthi lusetyenziswe. Oku kuyimfuneko ekusebenzeni ngokuqhelekileyo kwezixhobo zombane. Lo mhlaba kuthiwa usebenza, kwaye awukhuseli.

Ihostela idla ngokunikezwa ngombane we-220 V phakathi kwabaqhubi besigaba kunye nokungathathi hlangothi kwipaneli yombane. Kwindlu yangasese, igalelo linokuba ngama-380 V - amaqela amathathu kunye nokungathathi hlangothi. Emva koko iingcingo ziyahlula kwiziseko kunye nezixhobo zokukhanyisa kuwo onke amagumbi. Napha, nathi asifanele sikhohlwe ukuba kutheni ihlabathi lifuneka. Ukukhusela ukutshatyalaliswa kombane, omnye ucingo olusisiseko lubekwe kunye nabaqhubi nabangathathi hlangothi.

Ungazikhusela njani ukutshatyalaliswa kombane?

Enye indlela ekuphelisa ukutshatyalaliswa kombane okanye ekunciphiseni kakhulu ukufakwa kweso sixhobo. Kutheni sifuna i-loop yomhlaba? Kubalulekile kwizinto zokusebenza zasemzimbeni ngeendawo zetsimbi: iimashini zokuhlamba, izitofu zombane, iifriji, njl.

Xa ukwakhiwa kwezinto ezinokubakho kwizakhiwo zasekhaya, okwangoku kufuneka uye emhlabathini. Kodwa ngenxa yoko, kuyimfuneko yokuqala ukwenza ifowuni ngendlela yesakhiwo sensimbi, ukudala uqhagamshelwano lombane kunye nomhlaba. Inokuthi ibandakanyeke okanye iqukethe izixhobo zokuziphatha ezifakwe emhlabathini.

Ukugxila kwisiseko

Kutheni kubalulekile ukufaka izinto zombane zombane phambi kobuninzi bezinyithi okanye ezinye izinto? Lo mbuzo uqondakala kubantu abaninzi. Basenokungeniswa ngengozi xa ukugqithwa kweencambo kuphulwe okanye kukufutshane, okuyingozi kumntu ngexesha loqhagamshelwano.

Oku kusebenza nakwimimandla yensimbi yezibane kunye nama-chandeliers. Kwizakhiwo zokuhlala, umqhubi womhlaba we-2.5 mm ² wecandelo eliphambene nalo lifakwa kwipaneli yombane kwindawo nganye. Kutheni ndifuna i-socket eveziwe? Oku kuyimfuneko ukudibanisa umhlaba ngokusebenzisa umnxibelelwano walo kumncedisi wekhaya. Ngaphandle koko, kuya kuba mfuneko ukubeka itayiti kulo lonke ifulethi kwaye wenze udibaniso oluvela kuso ukuya kumzimba wefowuni nganye, engekho ubuchule obuhle.

Abafowunelwa be-grounding bahlelwe ukwenzela ukuba badibaniswe kuqala, ngokukhawuleza ukuba iplagi esuka kwintambo yomsebenzi wendlu ifakwe kwisiseko. Ukuba iziseko zidibaniswe ngoluhlu, ukuxhoma umxhasi kuncedwa ngokwahlukileyo kubo ngamnye kwibhokisi lokuhlangana.

Ukufakwa kwento

Ngoko, kutheni ufuna i-grounding house? Yenziwe ngoluhlobo lwe-loop evaliweyo. Ubume bunokuba yiyiphi na, kodwa umlinganiselo omncinci wezinto ezichithwayo usetshenzisiwe kwisimo esingunxantathu. Ngomlinganiselo wexantathu olinganayo, umsele unxweme emhlabathini ukuya kutsho kwe-1 m, kwaye iipayipi zensimbi okanye iikona ezide ubude be-2.5 m zivaliwe kwiindawo eziphezulu. Ukukhusela ukulwa nokubola, kungcono ukusebenzisa izinto kunye neengubo zethusi okanye zethusi. Musa ukupenda i-electrodes. Uyakwazi kuphela ukuyibeka indawo yokulondoloza.

I-electrodes kufuneka ikhuphe i-20 cm ukusuka kwinqanaba lomsele. Umqongqo uphawulwa ngombumba, kwaye umqhubi womhlaba ovela kwinto efanayo kuya endlwini ususwe kuwo. I-bolt ifakwe kwisiphelo samahhala, kwaye intambo ye-PE ye-6 mm ² okanye ngaphezulu ifakwe kwisithuba sombane. I-ohmmeter ihlola ukuxabiswa kombane wesiphaluka. Ngokwezidingo ze-PUE kwizakhiwo zokuhlala, akufanele kube ngaphezu kwama-30 Ohm.

Ukuba isibonakaliso sidlula umda osiweyo, iimbombo ezongezelelweyo zixutywa ngeenxa zonke, kwaye i-jumper yenziwe. Ngale ndlela, indawo yokuqhagamshelana phakathi kwesakhiwo kunye nomhlaba yanda. Ukunciphisa ukunyanzelwa kwesekethe, ucingo oluvela kulo luthatyathwa ngumqhubi weethusi kunye nokuqhuba okuphezulu. Emva kokuba umsele uzele umhlaba. Ilitye elichotshoziweyo, ukuhlenga okanye ukukwakha imfucuza ukufaka isicelo salokhu akuvumelekanga. Sebenzisa izinto ezigcina umswakama: udongwe, i-peat, i-loam.

Ukuxhotyiswa koqeqesho

Namhlanje nabantwana bayazi isizathu sokuba kudingeke ukuba kube lula. Kubalulekile ukuqinisekisa ukunciphisa ukuhluka kobunzima emhlabeni, ukwenzela ukuba i-voltage yomthamo kunye ne-step step voltage ayisebenzi kumntu. Kwiziko elisezantsi ngaphaya kweesekethe ezivaliweyo, ubuchule buhlukahluka ngokufanelekileyo, kwaye ngaphaya kwalo ukukhula kwemali kuvela ngokukhawuleza. Ukuthintela oku kungenzeki, imivimbo ensimbi engqameneyo exhunywe kwii-electrodes ingcwatywa ngaphandle.

Ngokuhambelana neemfuno ze-PUE, ukukhusela komhlaba kuyenziwe ngobhedu. Xa kuthengiswa kukho iisethi ezikhethekileyo, kodwa zineendleko eziphezulu. Ukuqulunqwa komhlaba kwezindlu zangasese, izitho zensimbi ziqhele ukusetyenziswa.

Isiphelo

Masibhale. Ngoko, kutheni ufuna i- grounding endlwini yangasese? Okokuqala, oku kudibaniswe nokukhusela abantu ekutshitshiselweni kwamandla kagesi. Kubalulekile ukuxhobisa ngokufanelekileyo umthamo womhlaba nokwenza uxhulumaniso olufanelekileyo lwamandla kagesi. Impilo nokhuseleko lwabaqeshi kuxhomekeke kwindlela ehlanganisiweyo kunye nezinto ezikhethiweyo.
